OG 58 没人问过的?

trade deficit  和 standard of living 是啥关系呀,谢谢

能不能说得详细点？

` Neither a rising standard of living nor balanced trade, by itself, establishes a country’s ability to compete in the international marketplace. Both are required simultaneously since standards of living can rise because of  growing trade deficits and trade can be balanced by means of a decline in a country’s standard of living.

   If the facts stated in the passage above are true, a proper test of a country’s ability to be competitive is its ability to  

    (A) balance its trade while its standard of living rises
    (B) balance its trade while its standard of living falls
    (C) increase trade deficits while its standard of living rises
    (D) decrease trade deficits while its standard of living falls
    (E) keep its standard of living constant while trade deficits rise.

答案是A、    请问此题的思路？

Neither a rising standard of living nor balanced trade, by itself, establishes a country’s ability to compete in the international marketplace. Both are required simultaneously

=>

a rising standard and balanced trade occur simutaneously .

another expression is '(A) balance its trade while its standard of living rises '( ps: while = simutaneously)

题目中不是说只有一个可以实现吗?

答案怎么可以两个同时实现?

真是豁然开朗阿！多谢！
